SPECIFICATION formingpart of Letters Patent No. 287,027, dated October23, 1883.

Application filed June is, 1883. (No modem IWAN, citizens of the UnitedStates, residing sents the blade of a ditching-hoe, of the usual at$treator, in the county of La Salle and State 'of Illinois, haveinvented certain new and useful- Improvements in Ditching-Hoes; and wedo hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked there- Figurel of the drawings is a perspective view ofa ditchinghoe constructed in accordance with our-"invention. Fig. 2 is adetail view, on an enlarged scale, of the divided shank; Fig. 3, asimilar view,'partly in section, showing the manner of connecting thehandle to the shank; and Fig. 4, detailed views of the handle.

The present invention has relation to that class of ditching-hoesprovided with adjustable handles, to admit of theblade and handle beingset at the desired angle with relation to each other to adapt the hoe tocertain class of work.

The objects of the invention are to form the shank of two separatesections, each of which is rigidly connected to the hoe-blade, and inconstructing the upper or free ends of the shank- 7 sections and thelower end of thehandle, whereby the latter is firmly held between thesection at any desired angle. These objects we attain by theconstruction, substantially as shown in the drawings, and hereinafterdescribed and v claimed.

In the accompanying drawings, A represpring metal from which blades ofthis character are usually made, and is concavo convex in form. v

To the blade A, midway of its ends, or nearly so, are riveted, orotherwise rigidly secured, the lower ends of a bifurcated shank, formedin two separate sections, 13 (3. Each section at its free or upper endis formed with clamps a, one of which, upon its inner face, has aratchet, b. j The clamps a have holes passing horizontally through themfor a screw-bolt, c, headed at one end and secured by a nut, d.

The interior faces of the sections B C have each a mortise, e, toreceive circular pins or tenons f, projecting from the sides of aratchethead, D, upon the hoe-handle E, the ratchethead engaging with theratchet-face 1) upon the clamp a of the section B. The clamps a haveconvex ends 9, to present as little surface as possible for theshoulders h to rest upon or come in contact, in order that the partswill not bind.

When it'is desired to adjust the handle, the nut upon the bolt isloosened, and the spring metal from which the hoe-blade is made willcause the shank-sections to separate, and also the clamps upon the endsthereof, to a suificient degree to disengage the ratchet-face of one ofthe clamps with the ratchet'head upon the handle, thus allowing thelatter to be turned tothe desired angle with the hoe-blade, after whichthe nut is again screwed up upon the bolt and the clamp brought and heldtightly against the ratchet-head. The ratch etteeth, as will beunderstood, prevent the handle from turning, and hold it in its adjustedposition with relation to the hoe-blade, while the pins or tenons uponthe ratchet head form a pivotal center upon which the handle turns.

We do not desire to confine our invention to the ratchet-teeth as shownin the drawings, as the same result may be obtained by a series of pinsarranged in a circle entering a series of holes, and in place ofproviding the head D with pins or tenons, mortises may be substituted,and the pins or tenons formed on the clamps, these changes being madewithout departing from the principle of our invention.

Having now fully described our invention,

what we claim as new, and desire to secure by Letters Patent, is- I Aditching-hoe having connected thereto a bifurcated shank formed insections, the upper or free ends thereof terminating in clamps andformed with mortises, and one of said clamps having a ratchet-face, incombination with a handle provided with a suitable head cast with tenonsextending from its sides and aratchethave hereunto subscribed our namesin the face to engage with that on the e1amp,said presence of twowitnesses.

mortises and tenons forming a pivotal center, HENRY IWVAN.

and a bolt passing through the clamps and LOUIS IYVAN. 5 heads,substantially as and for the purpose XVitnesses:

set forth. THEODORE RooKENFELLnR,

In testimony that we claim the above we H. F. HOWLAND.
